       udaddy - RDMA CM datagram setup and simple ping-pong test.


       udaddy [-s server_address] [-b bind_address] [-c connections]
                 [-C message_count] [-S message_size] [-p port_space]
       udaddy -s server_address [-b bind_address] [-c connections]
                 [-C message_count] [-S message_size] [-t tos] [-p port_space]


       Establishes  a  set  of  unreliable  RDMA  datagram communication paths
       between two nodes using the librdmacm, optionally  transfers  datagrams
       between the nodes, then tears down the communication.


       -s server_address
              The  network  name  or IP address of the server system listening
              for communication.  The used name or address must route over  an
              RDMA device.  This option must be specified by the client.

       -b bind_address
              The local network address to bind to.

       -c connections
              The  number  of  communication  paths  to  establish between the
              client  and  server.   The   test   uses   unreliable   datagram
              communication, so no actual connections are formed.  (default 1)

       -C message_count
              The  number  of  messages  to  transfer  over  each  connection.
              (default 10)

       -S message_size
              The size of each message transferred, in bytes.  This value must
              be smaller than the MTU of the underlying RDMA transport, or  an
              error will occur.  (default 100)

       -t tos Indicates  the type of service used for the communication.  Type
              of  service  is  implementation  dependent   based   on   subnet

       -p port_space
              The port space of the datagram communication.  May be either the
              RDMA UDP  (0x0111)  or  IPoIB  (0x0002)  port  space.   (default


       Basic  usage  is to start udaddy on a server system, then run udaddy -s
       server_name on a client system.

       Because this test maps RDMA resources to userspace, users  must  ensure
       that  they  have  available  system resources and permissions.  See the
       libibverbs README file for additional details.
